6 Claims. (o1. 91-14) The invention relates to a machine for use in thehanging of paper and adapted to apply paste to the back face of thepaper as the paper is unrolled, trim the edges, and measure the properlength for cutting off each strip so that the paper may be easilyremoved and applied toside walls or ceiling as desired. I

The object of the invention is toprovide a light and compact machinewhich can be easily dismantled for transportation, and which performsall of the operations necessary to unroll the paper, trim the edges,apply an even coat of paste of any desired thickness to the back face ofthe paper and measure the same the proper length for cutting off, all bythe manual operation of a single crank. v

A further object is to provide a machine-of the character referred towhich may be easily and readily opened up to give full access to theinterior for installing the paper and filling the paste trough or pan.

Another object is to provide a machine of this character in which thepaste is evenly distributed over the back face of the paper by meansof aspirally grooved roller and forced toward the center of the paper,preventing any paste from squeezing out at the end of the rollandgetting on the pattern of the paper.

snu another object of the invention is the provision of such a pasteapplying roller or cylinder, which is compactly located and arranged torevolve in the opposite direction to the movement of the paper, so asto' insure a proper amount of paste being applied to the paper.

Another object is to rotatably mount the paste control roller ineccentric bearings provided with a lever for adjusting the position ofthe roller for applying a light or heavy coating of paste upon thepaper, as desired.

A further object is to provide amachine of this character in which theworking parts may be quickly and easily dismantled or knocked down.

A still further object is the provision of a novel and simple device formeasuring the proper length of the paper for cutting off.

Still another object is the provision of means for splitting a strip ofpaper to any desired width as the same is unrolled and pasted.

A further object is the provision of means for controlling the roll ofpaper in the machine, comprising rod 'or shaft slidably mounted throughthe frame, and located through a spaced pair of disk flanges, one flangebeing fixed to the adjacent frame member, and the other flange being;eccentric bearing for adjusting movable toward and from the oppositeframe member to facilitate installing the paper roll, the movable flangebeing controlled from the outside of the frame by a spring loaded'barwhich is operated by a lever, the bar placing tension upon theend of thepaper roll.

A still further object is to provide a machine of this character havinga carrier or conveyor for drawing thepaper out of the machinabeing.geared to run slightly faster than the rolls, so

as to keep the paper under tension.

Still another object is to provide means for adjusting this carrier froma vertical to'nearly a horizontal position for measuring differentlengths of paper as may be required;

The above objects together with others which will be apparent from thedrawings and follow-" ing description or which may be later referred to,may be attained by constructing the improved paper hanging machine inthe manner illustrated in the accompanying drawings in which Figure 1 isa side elevation of the improved machine showing the same in operation;

by means of which the links may be swung upon The forward edge of thiscross bar comprises 8 a straight edge 58 and a hold-down roller 53 is Alever I03 is pivoted upon a bracket I04, fixed to the adjacent side ofthe frame, and provided 'with a depending lug I05 contacting the inner;surface of the spring arm 35, a hand knob I06 being provided upon 'saidlever for pulling the same outward to move the flange 34 outward so asto relieve the tension upon the paper roll and facilitate the removaland replacing of paper:

rolls, when the rod 33 is withdrawn.

The paper is unrolled fromsaid rod 33 and as indicated atfP is drawnover the top of the paste roll 30 so as to apply paste from the troughto the back or under surface of the paper which then passes around aroll36 fixed upon a shaft 31 journaled in bearings 38 located throughthe hinged side frames '45., a sprocket 39 being fixed upon one end ofsaid shaft for driving the roll 36 as will be later described. 1

a A grooved roller 40, preferably provided with; oppositely disposedspiral grooves 41 extending from the center toward eachend, is fixedupon a shaft 42 journaled ineccentric bearings 43 rotatably mountedthrough openings 44 in the side framesxl-l and provided'with levers 45foradjustingthe bearings in order to adjust the "positionof the'roll 40toward or from the roll 36 so as to evenly spread the paste in a film orcoat-' 3 ing of any desired 1 thickness entirely across the back orunder surface of the wall paper.

The side frames l4 have their upper-forward 1 portions-cut out as at 46to receive the hinged side 3 frame members I43, which are connectedtogather at their upper rear corners as by the cross bar, 41, hinges 41"connecting said A hinged frame comprising a pair of inverted cross barto journaled between the links 54. a

For the purpose of trimming the usual margin from. each side of the wallpaper a pair of adjustable disk knives 60 is provided, one knife beingadapted to trim each margin.

These disk knives are mounted upon blocks 6! 66 may be provided, beingcarried upon a block- 61 slidablyfmounted upon the rod 49 and.providedwith a springarm 68 having an angular upper end 6 9 terminatingin thedownturned lip 70 adapted to engage over the ledge 1| upon thecross piece 50 and provided .with a knob 12 for operating the same. Y

,A relatively narrow roller 13" may be carried in abracket 74- supportedupon the cross piece 50,; .said roller being adapted to hold the stripof wall; paper in contact with the upper side of the olle i -v Y I Aconveyor is mounted upon the machine and comprises a pair'gof side framemembers 15 between the lower ends of which is journaled a roller 16mounted in open bearings 11 fixed 'to' the upperedges of the side framesI4, curved bars 13 being hingedly mounted upon said bearings andadaptedto be, normally located in the position shown in Figs, 1, 3 and 4'forretaining the roller in'the bearings.

A-sprocket 19 is fixed upon the roller 76 and connected by a sprocketchain 80 with the sprocket 39 upon the roller 36, A hand crank sprocket19 for manually the upper portion of the side. frames 15, byanadjustable connection indicated generally at 81, the lower end of theU-shaped rod being adapted to be received by thelugs. 83, at the lowerrear corners ofv the side frames 14.0! against the stop pins 89' at theupperfrear corners of .said side frames.

A U-shaped bracket 90 is attached to the. upper end of the conveyor'bymeans of. brackets 9| and provided in each leg with a series of notches92 adapted to receive opposite ends of a rod 93 to which one end of thepaper strip may be con-' nected as at 94.

For the purpose of matching the strips a de-. pending rod 95 may beconnected to one of the brackets. 9| as by a screw 96 and provided withadjustable pointers 91..

A weighted spool 98 is provided to cooperate with the pointers 91 tomeasure the length of a strip as will be later described.

A metal plate I 01 may' be fixed transversely across the conveyorbeneath the straight edge 58' to that by means of a sharp knife or thelike the paper strip may be cut off at this point.

For the purpose of rotating the paste roll 30 in the direction of thearrow shown in Fig. 3,v sprockets I08 and I09 are fixed upon the shaftsof the conveyor roller 16 and the paste roller 39 respectively, and areconnected by a chain III].

In the operation of the machine to paste, trim and measure wall paper, aroll of paper is placed upon the spool33, as indicated at 34.

Paste is placed in the trough 24 and the end of the roll of wall paperis placed, with the back down over the paste roller 30, between theroller 36 and the grooved roller 40 and then under the roller 13 andhold-down roller 59 and onto the endless belt 85 of the conveyor.

The crank 8| is then rotated in a clockwise direction, rotating theconveyor belt 85 so that the upper side thereof travels upward, rotatingthe paste roll in clockwise direction so as to apply paste to the backof the strip of wall paper and rotating the roll 36 in a clockwisedirection so as to feed the strip of paper upward to the conveyor.

It should be understood that unless it is desired to split the strip ofpaper, the disk cutter 66 is moved away from the roll 36 by disengagingthe spring arm 68 from the cross piece 50.

It should also be understood that the margin trimming disk cutters 60are properly positioned to trim the margins from the strip of wallpaper.

The frame 15 of the carrier, or conveyor is graduated, preferably up toforty inches, for measuring short strips of paper, but for measuring andmatching longer strips for side walls and ceiling, the correct lengthmay be obtained by raising or lowering the carrier to the desiredadjustment, so that the required length of strip reaches the floor fromthe cutting-off point. For instance, if an eight foot length isrequired, for side walls, the carrier is so adjusted that when the endof the paper reaches the floor the paper may be cut oil at the straightedge 58, producing a strip eight feet along. By raising or lowering theouter end of the carrier, strips of greater or less length may beaccurately m'easured.

When strips of much greater length are required, the folder is used, asshown in Fig. 1. The paper is then run about six inches beyond the endof the carrier and a rod 93 is inserted under the paper and placed inthe outermost notch 92, and the end of the paper is press-ed over therod and against the pasted surface of the strip, as indicated at 94, andthe weighted roll 98 is placed on top of the paper, and the paper is runthrough the machine until the weighted roll reaches the floor, as shownin Fig.

1. This makes a singlefold, by which strips of from eleven to fourteenfeet may be measured.

To produce longer strips two or more folds may be used, it beingpossible to accurately measure up to the entire length'of a roll, ifdesired. For a double fold, when the paper reaches the position shown inFig. 1, a second rod 93 is placedbeneath the left hand side' 01 thedepending loop .of paper and pressed into the next adjacent notch 92 inthe folder arms, and the weighted roll 98 is placed on top of the paper,between the end of the carrier and said rod, and the machine is operatedas above described. Four such folds may be made, folding the entire rollof paper.

The matching of the paper is accomplished by means of the depending rod95 and the pair of pointers 91'. These pointers may be of differentcolors for convenience of the operator, one generally being green andthe other red. For a straight across match only one pointer is used, butfor a drop match the two pointers are used alternately.

Assuming that an eight foot strip is required, the machine should beoperated to run out eight feet of paper as above described; then if theplace on the margin where it says Join is at the cutting-off point 56,the machine is set for a straight across match by locating the greenpointer to register with the place marked Join. A

For a drop match pattern the other, or red pointer is then set midwaybetween the points marked Join, and each pointer is used alternately.

From the above it will be obvious that a very simple, efiicient andinexpensive apparatus is provided for quickly, easily and accuratelypasting, trimming and measuring strips of wall paper for hanging, and itwill be seen that the machine may be easily and quickly dismantled fortransporting or storing the same and may be easily assembled and placedin condition for op eration.
